The world isn't the only one talking about Mariah Carey's massive 35-carat engagement ring -- the singer herself is in disbelief over the massive rock.

A day after making her first public appearance since the proposal with fiance James Packer, Mariah joked to E! News on Jan. 29 about the big bling, "It's so heavy I can't lift my arm up!"

The super singer also dished on details of the proposal, which took place in New York City on Jan. 21. "It was very romantic," said Mariah.

The smitten kitten said of her billionaire businessman, "He's an exceptional person and really... it gets more romantic by the day, so it's very sweet."

Despite the two still being legally married to their exes, the "Obsessed" singer gave some insights on her upcoming wedding, which she says she wants to happen "somewhat soon" but that she doesn't want it to be over-the-top.

The 45-year-old songstress, who has been married twice before, said, "We are not doing a big wedding because he did two big weddings, and it's kind of like, 'I've done a big wedding [too]. We would rather make it beautiful but humble."
